Even though the Tsarnaev brothers made a violent dash from police, allegedly tossing homemade bombs as they fled, police told ABC News they so far have recovered only a single, semi-automatic handgun from the two men now accused of carrying off the Boston Marathon bombing.
The gun–a Ruger 9 mm semi-automatic handgun–presumably wielded by the older of the two brothers, Tamerlan Tsarnaev, was found by police at the shoot-out scene in Watertown, Mass. No guns were recovered from the boat where 19-year-old Dzhokhar Tsarnaev was eventually apprehended after a stand-off with police.
The serial number on the firearm was obliterated. Investigators are attempting to restore the serial number and trace its purchase history.
